CVSS: 6.5EPSS: 0%CPEs: 11EXPL: 0CVE-2019-11255 – Kubernetes CSI volume snapshot, cloning and resizing features can result in unauthorized volume data access or mutation
https://notcve.org/view.php?id=CVE-2019-11255
Improper input validation in Kubernetes CSI sidecar containers for external-provisioner (<v0.4.3, <v1.0.2, v1.1, <v1.2.2, <v1.3.1), external-snapshotter (<v0.4.2, <v1.0.2, v1.1, <1.2.2), and external-resizer (v0.1, v0.2) could result in unauthorized PersistentVolume data access or volume mutation during snapshot, restore from snapshot, cloning and resizing operations. Una comprobación de entrada inapropiada en contenedores sidecar de Kubernetes CSI para external-provisioner (versiones anteriores a v0.4.3, versiones anteriores a v1.0.2, v1.1, versiones anteriores a v1.2.2, versiones anteriores a v1.3.1), external-snapshotter (versiones anteriores a v0.4.2, versiones anteriores a v1. 0.2, v1.1, versiones anteriores a 1.2.2) y external-resizer (versiones v0.1, v0.2), podrían resultar en el acceso no autorizado a los datos PersistentVolume o la mutación del volumen durante una imagen instantánea, una restauración desde una imagen instantánea, la clonación y el cambio de tamaño. • https://access.redhat.com/errata/RHSA-2019:4054 https://access.redhat.com/errata/RHSA-2019:4096 https://access.redhat.com/errata/RHSA-2019:4099 https://access.redhat.com/errata/RHSA-2019:4225 https://github.com/kubernetes/kubernetes/issues/85233 https://groups.google.com/forum/#%21topic/kubernetes-security-announce/aXiYN0q4uIw https://security.netapp.com/advisory/ntap-20200810-0003 https://access.redhat.com/security/cve/CVE-2019-11255 https://bugzilla.redhat.com/show_bug.cgi?id=1 • CWE-20: Improper Input Validation •
CVSS: 2.6EPSS: 0%CPEs: 4EXPL: 0CVE-2018-1002102 – Kubernetes API server follows unvalidated redirects from streaming Kubelet endpoints
https://notcve.org/view.php?id=CVE-2018-1002102
Improper validation of URL redirection in the Kubernetes API server in versions prior to v1.14.0 allows an attacker-controlled Kubelet to redirect API server requests from streaming endpoints to arbitrary hosts. Impacted API servers will follow the redirect as a GET request with client-certificate credentials for authenticating to the Kubelet. Una comprobación inapropiada de un redireccionamiento de URL en el servidor Kubernetes API en versiones anteriores a v1.14.0, permite que un Kubelet controlado por el atacante redireccione las peticiones del servidor API desde endpoints de transmisión hacia hosts arbitrarios. Los servidores API impactados seguirán el redireccionamiento como una petición GET con credenciales de certificado del cliente para autenticarse en el Kubelet. • https://github.com/kubernetes/kubernetes/issues/85867 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Q56CULSH7F7BC4NPS67ZS23ZCLL5TIVK https://access.redhat.com/security/cve/CVE-2018-1002102 https://bugzilla.redhat.com/show_bug.cgi?id=1784602 • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •

https://notcve.org/view.php?id=CVE-2019-14891
A flaw was found in cri-o, as a result of all pod-related processes being placed in the same memory cgroup. This can result in container management (conmon) processes being killed if a workload process triggers an out-of-memory (OOM) condition for the cgroup. An attacker could abuse this flaw to get host network access on an cri-o host. Se encontró un fallo en cri-o, como un resultado de que todos los procesos relacionados con pod están colocados en el mismo grupo de memoria. Esto puede resultar en que se eliminen los procesos de administración de contenedores (conmon) si un proceso de carga de trabajo desencadena una condición de falta de memoria (OOM) para el cgroup. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14891 https://access.redhat.com/security/cve/CVE-2019-14891 https://bugzilla.redhat.com/show_bug.cgi?id=1772280 • CWE-460: Improper Cleanup on Thrown Exception CWE-754: Improper Check for Unusual or Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2019-10223
A security issue was discovered in the kube-state-metrics versions v1.7.0 and v1.7.1. An experimental feature was added to the v1.7.0 release that enabled annotations to be exposed as metrics. By default, the kube-state-metrics metrics only expose metadata about Secrets. However, a combination of the default `kubectl` behavior and this new feature can cause the entire secret content to end up in metric labels thus inadvertently exposing the secret content in metrics. This feature has been reverted and released as the v1.7.2 release. • http://www.openwall.com/lists/oss-security/2019/08/15/8 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10223 https://github.com/kubernetes/kube-state-metrics/releases/tag/v1.7.2 https://www.openwall.com/lists/oss-security/2019/08/09/1 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 5.7EPSS: 0%CPEs: 4EXPL: 0CVE-2019-11251 – kubectl cp allows symlink directory traversal
https://notcve.org/view.php?id=CVE-2019-11251
The Kubernetes kubectl cp command in versions 1.1-1.12, and versions prior to 1.13.11, 1.14.7, and 1.15.4 allows a combination of two symlinks provided by tar output of a malicious container to place a file outside of the destination directory specified in the kubectl cp invocation. This could be used to allow an attacker to place a nefarious file using a symlink, outside of the destination tree. El comando kubectl cp de Kubernetes en las versiones 1.1-1.12 y versiones anteriores a 1.13.11, 1.14.7 y 1.15.4, permite una combinación de dos enlaces simbólicos proporcionados mediante la salida tar de un contenedor malicioso para colocar un archivo fuera del directorio de destino especificado en la invocación de kubectl cp. Esto podría ser usado para permitir aun atacante colocar un archivo nefasto usando un enlace simbólico, fuera del árbol de destino. • https://github.com/kubernetes/kubernetes/issues/87773 https://groups.google.com/d/msg/kubernetes-announce/YYtEFdFimZ4/nZnOezZuBgAJ https://access.redhat.com/security/cve/CVE-2019-11251 https://bugzilla.redhat.com/show_bug.cgi?id=1753495 • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-61: UNIX Symbolic Link (Symlink) Following •
